Don't be confused, just read my answer above once more. Your argument is valid. Forget the light gathering arguments as those apply only to faint point sources, while most APs chase extended objects.
Let people explain the advantage of a 16" RC with 10um pixels over an 8" RC with 5um pixels. Apples with apples.
